Dangers of non-organic production

I came across this information while researching nuts, but the dangers of the chemicals are relevant to all types of agricultural production, and the effects on humanity, wildlife and the environment

Dangers of Non-Organic Nut production
Many pesticides abound in the non-organic production of nuts. Here are a few examples:
...
Atrazine is a herbicide used throughout the world for a varied range of uses including macadamia nut production. This environmental contaminant is regularly found in rain, surface, marine, and ground water and has been found in well water in the American Midwest. It is known to harm aquatic organisms like fish and frogs. There is some evidence that it may have a negative impact on human reproduction.
...
Cyfluthrin, which has been used for decades on nuts, is known to be highly toxic to marine and freshwater organisms.
...
Endosulfan is banned in many countries but legal in the United States and India, where it is used in cashew production. This pesticide presents health risks to farm workers and to those living near where the chemical is used. In December 2003, studies showed a link between endosulfan exposure and delayed sexual maturation in boys in India. Animal studies indicate that the pesticide attacks the central nervous system, and can cause damage to the kidneys, testes, and liver. It is highly toxic to animals and fish as well.
...
Methyl Bromide. Once harvested, nuts are often fumigated with methyl bromide, a toxic pesticide. While methyl bromide probably won’t cause any harm to you when you eat nuts or other treated crops, it is quite dangerous for the farm workers who use it. Also, it is such a large factor in ozone depletion that the countries around the world are phasing out its use.
...
Phosmet, used on pistachios, as well as apples and peaches, is highly toxic to honey bees.
